thanks for the archlinux-alternative.
As fas as I understand that thread it doesn't refer on gentoo and offers a non-systemd solution.
This is what I already have and use with the alternative system start via openrc .

Is there really no simple mount/unmount solution for systemd without stumbling across this permission-denied-problem ?
To be honest I don't need/want any automount possibilty
the

I had this problem too. The solution is easy but it's only a workaround with ugly side-effects.

Systemd wants to have /etc/mtab as a symlink to /proc/self/mounts. Because /etc/mtab keeps older entries even after a reboot. But setting the symlink causes the umount problem. So just revert /etc/mtab to an ordinary file and you'll be able to unmount nfs-partitions again as a user.

Code:

rm /etc/mtab
cat /proc/self/mounts > /etc/mtab

The side-effect is, that the output of mount contains some mount entries up to 20 times. Haven't noticed any unwanted behaviour yet.

At the first glance that seemed really compelling.
But today I did a mount / unmount with another gentoo-client machine.

The difference: no gnome3 an systemd-use flag.
I don't see a clear relationship.
But in the past weeks I observerd some strange side effects while running the instable setup with systemd and gnome3, even if I booted that machine with openrc (for example calibre couldn't detect ereader plugged in due to dependies between udisk and the systemd use flag, do booted with openrc it didn't work any more).
